yotebuster Report post Posted December 22, 2014 Do those winged eye cups from Amazon actually replace the factory eye piece or attach to the factory eye piece?they attach to the eye cup. They are made by SwarovskiThey replace the entire twist out. They also make your glasses fog up like crazy IMO. the ones I posted do not replace the twist out parts. If you check them out they have pictures in the link I postedRoger that. Those are different then the ones I had that replaced the whole twist out.who makes them? They should sound worth checking out. I believe they were the swaro ones. Now that I think about it, I think they snapped on, but you had to turn the twist outs all the way out and take off the old eye cup and these snapped on where the twist out was. So they didn't actually twist in where the eyecup went. I think I still have them laying around somewhere, I got them on a used set and hated that I would hot box the eye cup with them when it was cold out and they'd fog the ocular up.
